Hydrogen Seen - H2SE
Hydrogen Seen - H2SE
Main information on the Hydrogen selenide or " selenium hydride (H2SE), its physical characteristics, its health effects, the means of detecting it (H2SE gas detector) as well as the adapted respiratory protection devices (gas mask or assisted ventilation device with gas filter (b).
Main characteristics of hydrogen selenide (H2SE)
The Hydrogen selenide (H2SE)also called "Selenium hydride", is commonly used in the synthesis of compounds containing selenium. It is found in many industrial applications such as the electronics industry (component manufacturing), the metallurgical industry (preparation of alloys), the glass industry or paintings (pigmentation), the rubber industry (vulcanization) or in refining of copper.
Effects of hydrogen selenide on health
The Hydrogen selenide (H2SE) is an inorganic compound irritating for digestive mucousa, respiratory and eye. It is the most selenium compound toxic Of all, with a VME (exposure limit value) of 0.05 ppm. Even at extremely low concentrations, this compound has a very irritating odor that resembles that of horseradish or "leaking gas" and then gives up a rotten egg odor at higher concentrations.
H2SE gas detector (hydrogen selenide)
Although recognizable by its very irritating smell, only a H2SE gas detector can accurately measure the vapor concentrations of this extremely toxic compound, so we will move towards a portable or fixed hydrogen selenide detection in ppm. Or even in ppb (SPM Flex).
Respiratory protection selenide hydrogen (H2SE)
Hydrogen selenide is very irritating, we will focus on a complete mask for short-time interventions or to an assisted ventilation device (more comfortable) with type B anti-gas filters. If the concentrations exceed 60 times the Vlep, an insulating respiratory apparatus will be imperative.
